Quote:Nigel Leck, a software developer by day, was tired of arguing with anti-science crackpots on Twitter. So, like any good programmer, he wrote a script to do it for him.

The result is the Twitter chatbot @AI_AGW. Its operation is fairly simple: Every five minutes, it searches twitter for several hundred set phrases that tend to correspond to any of the usual tired arguments about how global warming isn't happening or humans aren't responsible for it.
